Chemical Structure

Saxagliptin Impurity 42 CAS 865999-67-3 chemical structure

Description

As a certified reference material (CRM), Saxagliptin Impurity 42 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Saxagliptin Impurity 42 (CAS 865999-67-3) is a certified pharmaceutical impurity reference standard with the molecular formula C6H8N2HCl and a molecular weight of 144.60 g/mol.

Based on its molecular formula C6H8N2HCl, Saxagliptin Impurity 42 contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 144.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
